"To aiZZ who-m if may concern? "Be it known that I, FRITZ Dannnnr, a citiingi is a specification.

n the production of non-condensable carbureted generator-gas or Water-gas heretofore the two following methods were in use. The one method consisted in separately vaporizing the hydrocarbon, mixing the vapors with the generator-gas or water-gas either after the gas has left the glowin fuel in the generator or in the uppermost layer of the lowing fuel and in converting the mixture into a fixed as by conducting it through a s ecial'cham er filled with glowing bodies or t ongh highly-heated tubes. The second method consisted in introducing the hydrocarbon into the zone of combustion in the furnace or generator, where it mostly burned and did-not carburet the heating-gas or en-' rich the same with carbon, but increased merely the percentage of carbon oxid and hydrogen.

My lnvention relates to an improved process of producing non-condensable' carbureted enerator or water gas, whereby a great saving in hydrocarbon is made and the process of carbureting considerably simplified.

According to my improved process the hydrocarbon is introduced from above into the glowing fuel and the zone of reduction. The

vertical section. of a gas-generator for canying out my improved process, although I do not limit myself to the construction shown.

This gas-generator comprises a furnace 71,

with the grate i, an air-tight fuel-charging device a of any known construction, a door g for removing the slag, an ash-pit door g, a blast-pipe f, a steam-pipe c at the lower part, and a dischargeipe (2 at the upper part of the generator. Vithin the furnace h is arranged a small shaft 0, which isopcn at -its lower end and. which extends downwardly through the zone of oxidation into the zone of reduction of the fuel. 5 denotes a sipbontube for the introduction of the liquid hydrocarbon.

' The improved generator is operated as follows: After kindling the fire in the usual manner the blast-air, either cold or warm, 1S admitted through the pipe f into the space beneath the grate i. When the combustion has proceeded so far that the fuel glows, the admission of the blast-air is stopped and the hydrocarbon liquid introduced through the siphon 1) into the shaft 0. x The liquid is vaporized by the great heat prevailing in the furnace h and the vapors raised to the tempera ture of the zone of reduction in the combustion-chamber. The hydrocarbon may even be superheated. Steam. is admitted from any source through the pipe 0 to the space heneath the grate i. The hydrocarbon passes from the shaft 0 to the zone of reduction of the glowing fuel, while the steam is acted upon by the latter in the well-known manner. The carbureted water-gas thus formed is then collected and conducted from the furnace it through the discharge-pipe d to a storage vcssel onto the point of use, the case may From time to time it will be necessary to 111- terrupt the supply of steam and hydrocarbon and to admit the blast-air in order to fire the fuel, which is supplemented by supplying additional quantities of fuel through the charging device a in the usual manner. When the fuel again attains the proper heat, the supply of blast-air is stopped and the steam is again turned on and hydrocarbon vapors supplied by the introduction of hydrocarbon into the shaft 0, said vapors being conducted from the latter into the zone of reduction. The length of the interruptions must be left to th judgment and experience of the operaton rlrom the drawing it is evident that the construction of the generator is considerably simplified. The process presents the important advantage that the quantity drocarbon required is far less than that which is necessary with other known methods for the following reasons: First, the hydrocarbon undergoes but one single heating and is not permitted to be burned, and, second, the

fixed carbureted gas thus obtained is superior of hy zoo to that obtained by other methods, since the hydrocarbon is enabled to act at the proper temperature in the zone of reduction upon the hydrogen in its nascent state.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The process herein described of making gas, which consists in vaporizing a liquid hydrocarbon by the heat of the combustionchamber, and then conducting the vapors thus generated into the zone of reduction of the glowing fuel a the temperature of such zone.

15 2. The process herein described of making gas, which consists in vaporizing the liquid hydrocarbon by the hat of the combustionchamber, then conducting the vapors thus generated into the zone of reduction at the temperature of such zone, and supplying the steam to the glowing fuel, and conducting off the resulting carbureted water-gas.

In testimon that I claim the foregoing as my invention have signed my name in presence of two subscribing witnesses WOLDEMAR HAUPI, HENRY HASPER.
